IMPROVEMENT IN WAGON-AXLES.

Specification forming part of Letters Patent N o. 167,843, datedSeptember 21, 1875; application filed July 21, 1875.

To all whom 'it may concern:

Be it known that we, JOSEPH R. LANTZ and THOMAS L. MITCHELL, ofMarrowbone, in the county of Moultrie and State of Illinois, haveinvented a new and valuable Im- I provement in Adjustable Axles; and wedo` hereby declare that the following isa full,

clear, and exact description of the construction and operation of thesame, reference being had to the annexed drawings, making a part of thisspeciiication, and to the letters and figures of reference markedthereon.

Figure 1 of the drawing is a representation of a side view of myinvention. Fig. 2 is a view showing the under side of the axle and box.Fig. '3 is a detached view of one of the axle-sections. Fig. 4 is an endsectional view, on an enlarged scale, of the box and axle.

This invention relates to extension or adjustable axles for wagons orother vehicles;

and consists in a divided axle of octagonal shape, its sections fittingin a hexagonallyformed sectional box7 by which construction theaxle-sections may be locked in place, al"- ter being adjusted to thedesired gage of treads, by tightening up of the box upon the axle; alsoadditionally securing it by setscrews upon the ends ofthe axle-sections,workin g in elongated slots formed in the upper section ot' the box, aswill be hereinafter more fully set forth.

-In the drawings, A represents the box, of any suitable metal, butpreferably of malleable cast-iron, and is formed in two sections, a a',the side pieces Haring outwardly sufciently to correspond when togetherwith the aring sides of the octagonal-shaped axle-sections B. The uppersection a of the box A is formed with elongated slots b and shoulders c,against which the heads of suitableset-screws d abut to prevent themfrom sliding or moving inI box, as vthe box-sections a a are firmly heldand clamped around the axle by the clamping-rod e.

To admit a free lateral adjustment of the axle-sections B within thebox, theyare formed with elongated slots g, for the passage of the boltsor rods e.

In place of the set-screws d a right-andleft hand screw-rod may beemployed, connected to the lower section of the box, and parallelthereto, while the ends of the axlesections are provided withdownwardly-projecting plates with screw-threaded openings, into whichthe right-and-left handed screwrod worksin adjusting the axle-sectionswithin the box.

The construction is very simple, adding no material cost to themanufacture of vehicles, and the operation of adjusting and setting theaxle-sections requires but a moments time,

it only being necessary to loosen the screwnuts f sufficiently torelieve the pressure of the sections a a upon the box B, and raise theset-screws d, when the axle-sections may be easily adjusted within thebox to the required distance, after which the nuts f are screwed back inplace, and the setscrews turned down until their heads are seatedagainst the shoulders c of the elongated slots b. 4

- Having now fully described the construction and operation of myinvention, what I claim as new, and desire to secure by Letters Patent,is-

l. The octagonal-shaped axle-sections B, in combination with thehexagonal box A, formed in sections a a', and bolt or rod e, fortightening and clamping the sections upon the axle, substantially asspecified. l

2. The hexagonalbox A, composed of the sections a a', the latter havingslot b and shoulders c, in combination with the Octagonal axle-sectionsB and set-screw d, substantially as and for the purpose set forth.

In testimony that we claim the above We have hereunto subscribed ournames in the presence of two witnesses.
